This is an outstanding manner to file. However, if the numerical partion could be exactly alligned it would be helpful, especially in filling out IRS forms

It was difficult for me (86 years old and somewhat "ok" with Windows 10) to figure how to send the document to my partners vie email for their markup, etc.

Admin just getting started with PDFfiller - so far this is great! Easy to use and appears to provide all desired options for helping to get our required results. THANKS PDFfiller!

There was one issue- the orange pen would pop up when highlighting a word or sentence, suggesting an edit I assume. I would click it then stare at a blue circle waiting waiting waiting. I would just close the entire website and come back.

What do you like best?
Ability to use templates was the most helpful. I like PDF filler because I can encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages. It's fairly easy to use but the interface isn't great.
What do you dislike?
The user interface is not intuitive for me. I liked all other features and don't have much bad to say. I'll continue to refer people.
Recommendations to others considering the product:
Great product!
What problems are you solving with the product? What benefits have you realized?
Filling out of legal documents for real estate transactions.

Subscription Help Review
I needed some assistance with my subscription and Kara was wonderful at understanding my needs and offering a suitable solution!

Reasonable but not fantastic
Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it.
The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use.
Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.
